Tokamak is a superconducting fusion device also known as the Korean artificial sun. It managed to maintain a high temperature plasma in South Korea for 20 seconds, and the temperature of the ions exceeded 100 million degrees Celsius, a new world record in South Korea. .

Scientists from Tokakak, a South Korean research institute for superconducting, broke their record in 2019 by keeping the temperature of the plasma above 100 million degrees for 20 seconds.

The KSTAR Research Center of the Korea Energy Research Institute (KFE) announced that it has successfully conducted research with SNU at Seoul National University and Columbia University, and is continuously operating the plasma at an ion temperature above 100 million degrees for 20 seconds. Celsius. This is one of the requirements for integration. Nuclear Energy in the KSTAR Plasma 2020 Movement.

In order to replicate the fusion reaction that takes place in the Sun on Earth, the hydrogen isotopes must be placed in a fusion apparatus (such as KSTAR) to form a plasma state in which the ions and electrons are separated and the ions must be heated and combined. Keep it at a high temperature.

To date, there are other fusion devices that can temporarily apply plasma at temperatures of 100 million degrees or more, but none of them can break barriers to keep the process going for 10 seconds or more.

Scientists are basically trying to replicate the conditions in our sun, and doing so on Earth's surface is a daunting effort, but it gives scientists an opportunity to study the behavior of the plasma and get different readings. .

The research aims to harness the power of fusion, and if that breakthrough can be achieved, it could completely change the way the world gains power.

The team is studying the rapid development of sun-like fusion reactions. After just two years of warming the plasma, the team extended its duration from 1.5 seconds to 20 seconds.

The goal of the KSTAR Research Center is for the ion temperature to exceed 100 million ° C by 2025 and to operate continuously for 300 seconds.
